To all whom z't may concern.'

Be it known that I, Hanny A. FISHER, a

lcitizen ofl'the United States, residing' at Plainville, county of Hartford, State of Connecticut, have invented an Improvementin Fasteners,4 for Panel-Cabinets, of which the following' is a specification.

This invention relates to panel cabinets, so called, that is cabinets adaptedior insertion in a Wall for receiving switches, :t'uses and other appliances used ini'naking', ceni' .tralizing and `controlling electricall circuits and connect-ions, andthe invention has for its object-to 'provide a simple and etlicient fastening device so constructed that the cover carrying the door4 of a panel cabinet I nay be easily and quickly secured in place, reversed or removed, thus providing'that thev door niay open either toward the vright or left, as rei:'erre d, and also doing' away with the 'necessity for setting' the cabinetphunb. As

cabinets 'of this character'haveheretofore been constructed, the covers were not adjustable relatively to the box -and as they were attached 'in place after thelatter was in- "serted in the wall, it has been necessary to use great care in rsetting' the box so that the cover when attached would bev practically plumb. AAnother ditliculty has been that the boxes were apt to get more or less battered and sprunggout of shape in shipnicnt'so that the screw holes in cover and boi; wouldl not elevation olf my novel cabinet as in use, theV `cover being' partly broken away; Fin'. 2 an elevation as soon from the rifn'ht in Fin'. l;

and provided with a suitable lock or catch.

The essential feature of the invention is that the edges of the box are provided with `flanges ll which may be turned either inward or outward atright angles to the sidtw ot' the box-but are preferably turned inward as shown in the drawing'. The cover is at tached to the box by means of clamping' plates l5 which are pivoted on't-he inner side of the cover, preferably by means of studs 1G which are rigidly secured in the plate ing'- interposcd between the plates and the cover and the heads of the studs being slotted to receive a screw driver by which the studs and plates may beturned from the outside. The/plates are locked in place by screws 18 which pass through the cover and engage the and turn in the cover, washers l7vbe' plates and act to clainp theni down upon the flanges ol the box.

ln use, having' set the box in the wall. the scre'vvs are turned out from the clamping plates, the plates turned. soy as to clear the flanges of the box, then the cover isset in place over the box, theelainping plates are turned over the flanges, as shown, after whichone of the clamping screws is inserted and the plate is clamped down upon the flange. The cover isthen squared up, after which `the rest of the serews'are turned in and all the plates are `clamped the flanges-of the box, locking the cover securely. in place. Any number of clamping plates may be used. In the present, instance I have shown two Aclamping plates upon each edge of the cover.

Having thus described my invention 'l claim:

l. The combination with a box having' an open 4en'd provided with a flange, a cover adapted tobe seated on said flange to close the open end of the box, a piv'ot extending' through and vrotatable inthe cover, a clamp ine' plate having one end rigidly fastened4 to the inner end of the pivot and adapted to engage the said flange, saidpivot having' its vouter end provided with means whereby it:

may be rotated from the exterior of the box to engage the plate with the said flange. and clamping' 'Ineans operable from theexterior oi the box and engaginaftlie free end of said clamping' -plate t0 bring' the latter into clamping' engagement with the flange.

2. The voi'nbination with a box having' an down upon open. end provided with a Harige, a Cover adapted to'be seated on the flange, pivots extending through and i'otgt-able in the cover, the ends of the pivots projectingbeyond opposite sides of the eover, clamping plates ezicill'igidiy fastened at one end to the inner eids of om, of said pivots, the outer ends of the pivots @eine1 provided with slotted heads whereby the pivots may be rotated to engage i screws extending through and operable from the outer side of the cover for engaging' the free ends of seid damping piates to bring' the latter into clan'ipinp;engagement with the flange, sqid clamping screws being provided with exterior slotted heads whereby they may be operated.

In testimony whereof I aiix my signature in presence of two Witnesses.
